+Events that can currently be listened to:
+'full': Emitted when the pool is dynamic and full.'busy': Emitted when the pool is busy.'error': Emitted when an uncaught error occurs.'taskError': Emitted when an error occurs while executing a task.When we receive a message from the worker we get a map entry and resolve/reject the promise based on the message.
